Q. Let y be defined implicitly by the equation.−10x3−8y3−x−10y=−91. Use implicit differentiation to find dxdy.
Write Equation: Write down the given equation.The given equation is −10x3−8y3−x−10y=−91.
Apply Differentiation: Apply implicit differentiation to both sides of the equation with respect to x. Differentiating term by term, we get: dxd(−10x3)+dxd(−8y3)+dxd(−x)+dxd(−10y)=dxd(−91)
Differentiate with Respect: Differentiate each term with respect to x. For the x terms, we use the power rule and the constant rule. For the y terms, we use the chain rule since y is a function of x. This gives us: −30x2−24y2dxdy−1−10dxdy=0
Isolate Terms: Isolate terms with dxdy on one side and the rest on the other side.−24y2dxdy−10dxdy=30x2+1
Factor Out: Factor out (dxdy) from the left side of the equation.(dxdy)(−24y2−10)=30x2+1
Solve for dxdy: Solve for dxdy.dxdy=−24y2−1030x2+1
